The remote host has a version of Java that is affected by multiple vulnerabilities.
The remote Mac OS X 10.7 or 10.8 host has a Java runtime that is missing the Java for OS X 2013-002 update, which updates the Java version to 1.6.0_43. It is, therefore, affected by two security vulnerabilities, the most serious of which may allow an untrusted Java applet to execute arbitrary code with the privileges of the current user outside the Java sandbox. Note that an exploit for CVE-2013-1493 has been observed in the wild.
Apply the Java for OS X 2013-002 update, which includes version 14.6.1 of the JavaVM Framework.
